Description
A former trademark for an aqueous solution of Formaldehyde at a concentration of 37% by weight (40% by volume). Current commercial formulations of formalin normally contains about 10-15% of methanol to prevent polymerization of the formaldehyde. Formaldehyde is a powerful reducing agent that will react with many materials on contact. It is used as a disinfectant, fumigant, embalming fluid, tanning agent, paint preservative, and photo processing chemical. Formalin has also been used as an aerosol and fumigant to treat algae on stone at the Lascaux caves (Lefevre 1974). When sprayed directly on a material, formalin may leave a white residue of paraformaldehyde.
